The angular velocity of a flywheel obeys the equa tion w(1) A Br2, where t is in seconds and A and B are con stants having numerical values 2.75 (for A) and 1.50 (for B). (a) What are the units of A and B if w, is in rad/s

Explanation:

Required

The units of A and B

From the question, we understand that:

This implies that each of and will have the same unit as

So, we have:

The unit of t is (s); So, the expression becomes

Divide both sides by

true tan speed = ang vel x radius
